我们提出了一个标准,用于确定X线的方向时,两个区域的等离子体与任意密度,温度和磁场进行重联。X线指向最大化(适当定义的)表征重连流出的阿尔文速度的方向。在许多情况下,一个很好的近似是X线平分磁场形成的角度。
We propose a criterion for identifying the orientation of the X‐line when two regions of plasma with arbitrary densities, temperatures, and magnetic fields undergo reconnection. The X‐line points in the direction that maximizes the (suitably‐defined) Alfvén speed characterizing the reconnection outflow. For many situations a good approximation is that the X‐line bisects the angle formed by the magnetic fields.
